Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the ability to:

capture customer functional needs for cabling system
apply industry standards, regulations and codes when designing the wiring system for customer premises
develop a detailed design in compliance with industry practices, including signal losses and/or expected measurements that need to be achieved at wallplates
document the design, including a bill of materials, schedule of work and associated costs.
Context of and specific resources for assessment
Assessment must ensure:

candidate is provided with a contemporary dwelling design, which covers all functional requirements of a modern home
candidate has access to all current standards, codes and regulations.
Method of assessment
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct observation of the candidate communicating with the customer
review of the planning sheets used by the candidate in developing the design
oral and written questioning to assess candidate skills and knowledge.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICTTEN4229B Design, install and configure a customer smart technology network.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.
